Research indicates that cursing lessens the sensation of pain, according to an article on Web MD.
We cursaholics know well the balm of the F-bomb in situations that deal both actual and emotional pain. Admittedly, some of us resort to these painkillers too frequently, but it's no different from abusing over-the-counter or prescription remedies.

"I want you to smoke one doobie every six hours and say $&^$^%#! *&%*&! @$%#&%! once every four hours. If you need to, you can increase the dosage of $&^$^%#! *&%*&! @$%#&%! without too many side effects. Just beware that while marijuana carries no risk of addiction, you may find $&^$^%#! *&%*&! @$%#&%! to be very habit forming."
